<br />from the basin (Steele and others, 1979). The effects of reservoir development on <br />streamflow and the effects on fish and wildlife habitat need to be determined. <br />Accordingly, the U.S. Fish and Wildlife Service requested that the U.S. Geological <br />Survey determine the effects of potential reservoir configurations and various <br />allocations for irrigation and transmountain diversions on the quantity of stream- <br />flow throughout the Yampa River basin. <br /> <br />In this study, a multi reservoir-flow model was used to simulate the effects <br />of various configurations of 17 proposed reservoirs, a proposed transmountain di- <br />version, and a proposed addition to a second existing transmountain diversion, on <br />streamflow in the Yampa River basin. The 17 proposed reservoirs are the larger of <br />the total 35 reservoirs being considered for construction in the basin. While the <br />geohydrologic characteristics of the Yampa River basin are well known, thephysi- <br />cal characteristics and operating schedules of the reservoirs and transmountain <br />diversions are speculative, as are the flows resulting from the model simulations. <br />To obtain some knowledge of the possible effects on streamflow, five potential op- <br />tions including one representing historical conditions (no additional reservoir <br />development) and four representing various degrees of reservoir and transmountain- <br />diversion development were studied. This study is an extension of earlier reser- <br />voir modeling for the Yampa River basin (Adams and others, 1982). <br /> <br />By varying the percentages of agricultural and transmountain diversions with- <br />in each proposed reservoir-development option studied, different degrees of devel- <br />opment were simulated, thus providing results for a greater range of alternatives. <br />The results of these simulations will provide water managers and planners with <br />some insight into how proposed surface-water developments will affect minimum <br />streamflows. <br /> <br />Results for nine representative control points are presented in this report. <br />Results for the remaining 38 control points may be obtained from the U.S. Geologi- <br />cal Survey for the cost of computer and reproduction time. <br /> <br />MODEL DESCRIPTION <br /> <br />The multireservoir-simulation model used in this study was the HEC-3 multi- <br />reservoir-flow model developed by the U.S. Army, Corps of Engineers (1968) to do <br />multipurpose, multi reservoir routing of streamflow within a river basin. For this <br />study, the Yampa River basin was simulated by 47 control points, arranged in down- <br />stream order, representing either a reservoir, a diversion or return-flow point, a <br />confluence of streams, or a stream reach where fish and wildlife habitat is of <br />interest. At all reservoir control points, monthly values were specified for net <br />evaporation (evaporation minus precipitation), downstream discharge-channel capac- <br />ities, and reservoir geometry (including elevation-area and elevation-volume <br />tables). Storage in each reservoir was divided into six storage and surface-area <br />increments to faci'litate approximate simultaneous adjustment of all reservoir <br />levels throughout the basin. Monthly diversions, return flows to the next down- <br />stream control point, and estimates of consumptive use were specified at all <br />diversion control points. Between all control points, incremental inflow was <br />computed on the basis of available streamflow records. <br /> <br />3 <br />
